OIL BURNER FOB STOVES.

Application filed August 4, 1922. Serial No. 579,749.

To all to ham it may concern. 7

Be it known that I, WALTER E. HennarnLn, a citizen of the United States, and a resident of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Oil Burners for Stoves; and I do hereby declare the following to be a full, clear and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in oil burners for stoves and more particularly to the wick operating means for the same, one object of the invention being to provide adjustable stop devices which shall be simple in construction and readily operable to regulate and control the limit to which it may be desired the wick shall be permitted to be raised, and by means of which also the wick may be lowered sufficiently to cause a flame thereon to be extinguished.

\Vith this and other objects in view, the invention consists in certain novel features of construction and combinations of parts as hereinafter set forthand' pointed out in the claims.

In the accompanying drawings, Figure 1 is a view in elevation showing the application of my improvements to a burner. Figure 2 is a View partly in section and partly in elevation showing the wick-operating and stop devices. Figures 3 and 1 are end views showing different positions which the wick operating devices may be caused to assume; Figure 5 is a View partly in elevation and partly in section on the line 5-5 of Figure 1, and Figure 6 is a view on the line 66 of Figure 2.

The burner 1 to which my improvments may be applied may comprise concentric outer and inner shells 2 and 3 which receive a wick 4 between them, said wick having secured thereto a perforated carrier 5 with which the pinion for raising and lowering the wick meshes as is well konwn in burners of the type to which my improvements are applied.

The outer shell of the burner has secured thereto a housing 6 which forms a chamber communicating with the wick compartment formed between the burner shells and with said chamber a connection 7 for an oil pipe communicates.

An inclined tube'8 is rigid at one end with the housing 6 and projects upwardly and laterally from the'burner,-said tube constituting a mounting for awick operating spindle 9 provided at its lower end with a pinion 10 to mesh with the perforated wick carrier for effecting the raising and lowering of the wick. The tube 8 is provided near its free end with a disk 11 having a depressed central portion made rigid with said tube and at one point the said disk 11 is provided with a stop lug 12 which may be formed integral with and bent up from the metal of the disk. i-

The spindle 9 projects an appreciable distance beyond the free end of the tube 8 as indicated at.13 and has rigidly secured to its free end, a manually operable wheel 1% which is provided with an annular series of perforations 15. Disposed between thediskll and the oper ating wheel 14 is a spring yoke or member 16, the respective members of which are made with perforations 17 for the accommodation of the portion 13 of the spindle 9 on which said spring yoke or memberis freely mounted to turn. The lower member 18 of the spring yoke bears upon the disk 11 and is provided with a finger 19 to co-operate with the stop lug 12 on the .disk,'while the upper member 20 of the springyoke bears against the under face of the operat-- ingwheel 14 and is provided witha tooth or lug 21' to enter one of the-perforations in said wheel. The upper member 20 of the spring yoke is also provided with an arm or finger piece 22 by means of which said upper member of the yoke may be depressed to release the spring device from the operating wheel.

When the wick is being fed into the burner, the spring yoke will be released from the operating wheel so that the latter may be turned freely to effect the downward feeding of the wick until the upper end of the latter becomes flush with the upper ends of the burner shells. The spring yoke while still released from the operating wheel may then be turned to assume a position with the finger 19 diametrically opposite the stop lug 12 and then released'to cause the tooth or lug 21 to enter one of the perforations 15 in the operating wheel, thus locking said spring yoke and operating wheel together. By now turning the operating wheel a limited distance to the right the wick may be raised sufficiently for starting purposes but it cannot be raised higher than will be per- 'mitted by engagement of the finger 19 with the stop lug 12. If desired thespring yoke may first be locked to the operating wheel so that the finger 19 will be disposed a comparatively short distance from the stop lug 12 so that the limit of upward movement of the wickfor starting purposes may be effected by turning the operating wheel untilthefinger 19 engages said stop 12. The spring'yoke may then be released from the operating wheel, turned to the left any de sired distance and then permitted to again interlock with'the operating Wheel so that vices, may be adjusted to any desired position relatively to the opera-tlng wheel so that the limit-ofheight to which the wick may be raised may be predeterminedand controlled.

Slight changes might be madein the (le tails ofconstruction of my invention with- I out departing from the'spiritof the latter or limiting its scope and hence I do not wish to *restrict myself to the precise: details herein set forth. I Having fullydescribed my invention what I claim as new, and desire to secure by Letters Patenhis: s v

liThe combination with a burner, a tube secured thereto, and a disk rigid'with said tube andprovided with astop, of a wick operating spindle passing through'f said tube and provided with a manually operable member, and a yoke of spring metal disposed between said disk and manually op erable memberand adjustably cooperable raised.

2; The combination with a burner and a tube secured thereto and provided with a disk having a stop, a wick operating spindle passing through said tube, an operating wheel rigid with thefree end of said spindle and having a plurality of perforations-a yoke of spring metal disposed between said disk and wheel and mounted to be turned or adjusted independently of the spindle, one arm or member of saidyoke being cooperable withthe stop on said disk and the other memberof said yoke having a finger piece, and a'lug rigid with the last mentioned yoke member to enterany one of the perforations in the operating wheel,

3. The combination witha burner and a tube secured thereto and provided at its free end with a disk having a fixed stop projecting therefrom, ofa wick operating spindle passing through said tube and projecting beyond the free end thereof, an opcrating wheel rigid with the free end of said spindleand provided with'a' plurality of perforations, a yoke of spring metal disposed between said disk and wheel and freely mounted on the projecting portion of the spindle, one member of said yoke having a part to engage the stop on said disk and the other member of said yoke'havinga projectionto enter any one of the per fora'tions in the operating wheel.

In testimony whereof, Ihave signed this specification in the ingfwit-nesses.
